In Brief
SIS is the only international school in Mumbai with a boarding option, which makes it genuinely unique for families whose situation calls for it. For day families in the far north or looking for value-range IB fees, it is worth a visit - but read the mixed reviews on admissions staff and boarding facilities before committing.
Established in 1959, Singapore International School Mumbai is one of the city's oldest international schools and the only one offering boarding accommodation. The 10-acre campus in Dahisar East is the largest physical footprint of any international school in Mumbai, with film and music studios, sports facilities, and space for students from 26-plus nationalities. Day and boarding students follow the Singapore curriculum through primary, Cambridge IGCSE in the middle years, and IB Diploma at Grade 11-12. Round Square membership and College Board affiliation place it alongside globally connected schools.
CCLP ranks it 9th nationally for the 2025-26 school year, and the CIS accreditation confirms programme quality at an institutional level. Fees are in the INR 6 lakh range for day students, rising to around INR 8 lakh for boarders - among the more accessible price points for an IB school in Mumbai, particularly given the campus size and boarding option. For families stationed in the far north of Mumbai (Dahisar, Mira Road, Virar corridor) or those who need a boarding solution for older children, SIS fills a gap no other Mumbai school covers.
The mixed reviews are worth taking seriously. Justdial ratings of 4.1 across 508 reviews indicate a broadly positive base, but recurring themes around admissions staff responsiveness and boarding facility standards appear in independent feedback. These are not dealbreakers, but worth probing directly - ask for a campus tour that includes the boarding block, and speak to at least two boarding parents before deciding. The far-north location (NH8 corridor, Dahisar East) is a real constraint for families based in South Mumbai or BKC.
What parents value
- –Mumbai's only international school with boarding - a genuine niche for families who need that option. 10-acre campus is the largest of any international school in the city, with film studios, music facilities, and sports grounds.
- –CCLP 9th nationally in 2025-26 and CIS-accredited. Fees at INR 6-8 lakh per year are accessible relative to Mumbai's premium IB schools. Students from 26-plus nationalities and Round Square affiliation.
Points of consideration
- –Dahisar East location on NH8 is remote for families in South Mumbai, BKC, or the western suburbs. Factor in commute or boarding cost before comparing against more central schools.
- –Mixed feedback on admissions staff and boarding facilities appears in independent reviews. Visit the boarding block and speak to current boarding families before committing - particularly if boarding is the primary reason for choosing the school.
